I know which charts are being passed around and if that chart doesn't say it is flowed in ALCOHOL at the top then it was the one that was flowed in water. I have corrected flow charts that are for alcohol. I just don't want you guys to blow up your motors. Double check them to see if it says it was ALCOHOL at the top of the page.

Mike, do you know why they flowed the jets with water as there's so much difference between that and alky? I realise that, in the end, as long as someone knows his engine well and knows what changes to make, it doesn't really matter. But, as has been said here many times, if one wants to compare his tune up with someone elses, you need to be 'comparing apples with apples'. It makes sense to do all your testing/tuning/flowing with the very same liquid you're going to be using.

It is common to flow pumps and fuel systems with water and then make the correction after. The correction is simple math. It is cheaper and safer to use water or another liquid with the same specific gravity as alcohol. Just as a warning to all if that jet chart doesn't say alcohol was used then check and see what was used. I also circulated to flow charts a year or two ago thinking they were flowed with alcohol and then found out after the fact the company used water but didn't tell me and didn't state it on the flow sheets.
